This is the second season in a row that Biarrtiz gave qualified for the Amlin quarters and last year the two-time Heineken Cup finalists showed they can go all the way by beating Toulon in the final.
The Frenchmen became used to winning on the road in England last year, defeating London Wasps at Adams Park in the quarter-finals and then Toulon at Twickenham Stoop.
The big worry for Gloucester is that one of their former players, Dimitri Yachvili, is all set to return and potentially kick them out of the tournament. The French scrum half has been in fine form in the last two weekends in the Top 14, scoring 14 points in the win over Grenoble having plundered 22 the previous weekend in the 32-28 home victory over ASM Clermont Auvergne.
- This will be Gloucester's fourth quarter-final appearance in the tournament. The Cherry and Whites have won two of the previous three.
- Freddie Burns has landed more kicks at goal than any other player in this season's Amlin Challenge Cup, landing 24/28 (86%) to date. Only one player (Nicolas Laharrague) who has attempted over 10 place kicks has a better success rate.
- Fabien Barcella of Biarritz, who are reigning Amlin Challenge Cup champions, conceded 12 penalties in the pool stage of the Heineken Cup - a competition high figure.
- These two clubs have clashed on four occasions in the Heineken Cup, securing two wins apiece. All four games were won by the home side.
- Both Amlin Challenge Cup meetings were won by the home side as well.
- Gloucester have won all six of their Amlin Challenge Cup matches this season and their last nine overall, their best run of form in the tournament.
